President Obama on Thursday pledged continual assistance to the typhoon-ravaged Philippine islands and urged Americans to help however they can.

“One of our core principles is when our friends are in trouble, America helps,” President Obama said at a news conference. “As I told President Aquino earlier this week, the United States will continue to offer whatever assistance we can. Our military personnel and USAID team do this better than anybody in the world and they’ve already been on the ground working tirelessly to deliver food, water, medicine, shelter and to help with airlift.”

Panic continues to heighten in the devastatation-gripped Philippines where survivors of Typhoon Haiyan are struggling over food shortages, lack of water, and medical aid since the storm made landfall Nov. 8. Relief workers and foreign governments are tirelessly working on the ground to offer relief to the 11.5 million people who have been affected and over 615,000 displaced by the typhoon.

Thursday’s arrival of the aircraft carrier USS George Washington will be a major addition to the international aid already on the ground. The carrier will set up off the coast of Samar Island near the Gulf of Leyte to first assess the overall damage and provide medical supplies and water. The George Washington carrying purifying machines that can purify up to 100,000 gallons of water per day.

The fleet will also bring 21 helicopters to the area, joining six American ships in the area, including a destroyer and two supply vessels.

Access to water has become a high priority for survivors. NBC News chief medical editor Nancy Snyderman spoke to doctors on the ground who have told her that people are boiling their water even though there have been increasing cases of severe dehydration and dysentery.

Six days after the disaster when when the storm’s 195-mph-winds and wall of water slammed into the country, hundreds of unidentified victims were buried in mass graves after workers on Thursday began collecting the bodies of victims of for burial.

With the risk of spreading water-borne diseases such as dysentery, cholera and typhoid fever becoming critical each day, city officials of Tacloban – the capital of Leyte province, the area that was hit the hardest – said they must put public safety ahead of funeral ceremonies.

“It is difficult because there is an urgency for sanitation, and to boost morale and avoid more psychological stress,” said Police Superintendent Pierre Carpio.

Official confirmed deaths stood at 2,357, a figure that is expected to rise when further information is collected from other affected areas. Aid workers say the true death toll could be much higher.

After some initial confusion, a spokesperson for the UN’s Office for the Coordination of Humanitarian Affairs said 4,460 people have been confirmed dead. President Aquino said Tuesday estimated there being between 2,000 to 2,500 fatalities, significantly lower than the earlier estimate of 10,000 dead.

“At this time, it is definitely not 10,000,” Cabinet Secretary Rene Almendras said at a news conference. “There has been a body count basd on the dead lying in the streets but we can’t be accurate because there is still, some people say, there are people buried in certain areas.”
